Air Blower Confusion

(1/3) > >>

dazedandconfused:
Do all spas have air blowers?  What is an air blower?

For example, on a HS, you have 2 size knobs - the bigger one is a diverter (diverting ONLY WATER between regions in the spa) and the smaller one is for ONLY adjusting the force of WATER in that respective seat?

I am thinking that an air bloer is for the aroma therapy on the Sundance line?

I am confused!

ZzTop:
An air blower is a separate air pump which forces air throught the jets.

No most spas do not have air blowers.  The consensus seems to be that they do not add much to jet therapy and tend to introduce cold air into the water which lowers the temperature.   The only real advantage I can see is in very hot weather it might be refreshing.  It is a personal choice, but remember the more features, the more things to fail or go wrong.

Do not confuse an air blower with the standard air controls which are on every spa which work from suction (venturi) of the pumped water pulling air into each jet.  You will find a diverter or diverters on your spa which controls the amount of air introduced.  This is a good thing and all that is really needed.

Aroma therapy can be introduced simply by pouring a liquid scent (one approved for spa use) and usually a teaspoon full directly into the spa water.  For most people it is not a big thing.

Thanks

But what is an air blower - does it just blow air thru the nozzles along with water?

Does SD, HS, D1 use air blowers?

Brewman:
An air blower is just that.  Only air is blown thru special "jets" located throughout the tub.  No water is pumped thru these.  There is a special air pump made for this purpose, doesn't use the main pumps.
This is how the aroma therapy on our Optima works.  
I don't think all spas have this.  We like the affect, but it does tend to introduce cooler air into the water, which is something the heater takes care of in a couple minutes.

Perhaps you are confusing the air mixture controls for the therapy jets.  With these, you open them to add air to the water running thru the jets.  I think the effect with air mixed in is better than just water alone.

Brew and ZZ have it. Air blowers add very little if anything to a spa IMO and nothing is free so I prefer not to have them if I'm buying. I'm not saying they are a negative but they are not needed IMO.
